Definitions

  • the present invention generally relates to the art of electrical connectors and, particularly, to electrical connectors for mounting to a support or panel.
  • the mating connector part that makes snap fit engagement with the support panel usually comprises a circumferential sealing joint.
  • This sealing joint is fixed on a front surface of said mating connector part that abuts against the panel upon engagement. Even if the sealing joint can slightly cushion movements of the electrical connector with respect to the panel in the insertion direction of the mating connector, it has to be noted that vibrations occurring owing to the clearance between connector and panel cannot be eliminated by means of said sealing joint.
  • US Patent 5660564 describes a connector arrangement corresponding to the non-characterising portion of claim 1.
  • an object of the present invention to provide for a connector to panel assembly that is able to absorb and eliminate vibrations caused by a clearance between the connector and the panel. It is also an object of the invention to prevent these vibrations from generating disturbing noise and from deteriorating mechanical elements. This applies particularly to the automotive industry where vibrations may create noise bothering the passengers, and where vibrations may also deteriorate other mechanical pieces of the car.
  • the present invention provides a connector arrangement according to claim 1.
  • the support panel comprises a first section and a second section that are adjacent to said cutout.
  • the electrical connector comprises jamming means adapted for engaging said first section of said panel from a first side of said panel, and a first abutment portion.
  • a grommet that is adapted to be mounted on the support panel from a second side of said panel comprises a grommet frame, first latching means for engaging said first
  • Said second latching means of the grommet is adapted to enter a gap between the support panel and the electrical connector, and to make a snap fit with said second section of said panel when assembled. Additionally in case the jamming means of the electrical connector do not fully engage said first section of said panel, the completion of the snap fit of said second latching means is causing the jamming means to fully engage said first section.
  • This second latching means is firmly fixed to the grommet by means of support means.
  • Said support means can be conically-shaped to guide said second latching means through the cutout.
  • Said support means can be further bended or turned in order to compensate for tolerances in the mounted assembly.
  • the absorption of vibrations caused by clearance between the connector and the panel is achieved by means of one or a plurality of buffers that are formed between the grommet frame and said second abutment portion of the grommet.
  • the buffers can be made of soft rubber material or alternatively of a material having absorption properties.
  • the grommet frame and the buffer can be one piece.
  • the electrical connector arrangement of the invention generally involves three main components, i.e. an electrical connector 2, a support panel 1, board or frame to which the connector 2 is to be mounted, and a grommet 7 which is adapted to serve as a fastening element to maintain the connector 2 securely mounted on, to or into the support panel 1.
  • the electrical connector 2 to be fixed to the support panel 1 is comprised of a first connector 68 or receptacle mountable on the support panel 1 e.g. of a door or a body of an automotive vehicle, and a second connector 66 or plug that is mateable with said first connector 68.
  • the second connector 66 see Fig. 13 , is in the embodiment the removable portion of the electrical connector 2.
  • the first connector 68 as shown in Fig. 1 , comprises first cavities 69 and first terminal fittings (not shown) to be accommodated in said first cavities 68 such that, on mating said second connector 66 with said first connector 68, leading ends of the first terminal fittings can be connected to second terminal fittings (not shown) accommodated in second cavities 70, see Fig. 13 of the second connector 66.
  • the first connector 68 comprises a casing 20.
  • said casing 20 has essentially a parallelepipedic shape.
  • the invention is not limited to the embodiment according to Figs. 1 to 4 and other forms of the casing 20 are possible, e.g. oval or rounded shapes.
  • the casing 20 of the first connector 68 has a basis or rear surface 21 contained in a plane defined by axes X and Y.
  • Two parallel longitudinal surfaces 22, 23 and two parallel transversal surfaces 24, 25 extends from the edges of the rear surface 21 perpendicularly to the plane of the rear surface 21 along an axis Z.
  • a front edge 26 of the casing 20 is defined by the free ends 27, 28 of the two longitudinal surfaces 22, 23 and by the free ends 29, 30 of the two transversal surfaces 24, 25.
  • the front edge 26 is comprised in a plane parallel to the rear surface 21 and constitutes the external boundary of a front opening 31 of the casing 20 through which the second connector 66 can be inserted in the first connector 68.
  • the front edge 26 is designed to abut at least partially against the support panel 1.
  • a first or top one of the parallel transversal surfaces, or top surface 24, is essentially plane and comprises at least one and preferably two top inclines 5a, 5b being located at each side of the top surface 24 adjacent to the two parallel longitudinal surfaces 22, 23. While the top surface 24 extends along axis Z up to corresponding free end 29 of the front edge 26, each top incline 5a, 5b extends up to the front edge 26 with an angle a with respect to axis Z towards the internal part of the casing 20, see Fig. 2 .
  • Said angle ⁇ is preferably small and preferably below 20° such that, if the casing 20 is only allowed to move along axis X, a mechanical piece translating parallel to the top surface 24 may cause, on abutting against the top inclines 5a, 5b, a movement of the casing 20 along said axis X perpendicularly to the translation movement of said mechanical piece.
  • the other or bottom one of the parallel transversal surfaces 24, 25 is also referred to as bottom surface 25 in the following description.
  • Jamming items of a first type 3a, 3b and jamming items of a second type 3c, 3d are formed on the casing 20 of the electrical connector 2 in order to guide said electrical connector 2 while mounting it to the support panel 1.
  • the first embodiment shown in Figs. 1 to 14 comprises four such jamming items, each of which is located in the vicinity of a corner of the front edge 26 of the casing 20. According to the invention, a stable mounting of the electrical connector 2 generally requires at least two jamming items.
  • each jamming item 3a, 3b, 3c, 3d comprises an abutment portion 36, a supporting portion 37, and a jamming slot 38.
  • the jamming item 3a, 3b, 3c, 3d is supported and maintained to the casing 20 by the supporting portion 37.
  • the abutment portion 36 is a protrusion of the casing 20 beyond the surface defined by the front edge 26.
  • Each jamming slot 38 opens in the same direction that is the direction opposite to direction X.
  • the opening width of the jamming slot 38 is equal or slightly superior to the thickness of the support panel 1, and is such that the support panel 1 can be inserted in said slot 38.
  • Each locking latch 4a, 4b comprises a locking arm 42 and a locking projection 43.
  • the locking arm 42 extends from the first connector 68 essentially parallel to the front edge 26 according to the direction opposite to direction X. Behind each locking arm 42, i.e. between each locking arm 42 and the longitudinal surface 22, 23 on which it is disposed, a slot 44 is formed to allow a deflection of said locking arm 42 towards the rear surface 21 of the first connector 68.
  • the fist connector 68 is thus adapted to be inserted in a cutout 39 of the support panel 1 according to a first insertion direction defined by first arrow 40, said first insertion direction being preferably perpendicular to the support panel 1 in a direction opposite to direction Z, see Figs. 1 and 2 .
  • the support panel 1 is preferably made of sheet metal and may be part of the car body of an automobile.
  • the cutout 39 is defined by an opening adapted to the form of the casing 20 of first connector 68.
  • said cutout 39 accordingly has a substantially rectangular opening along the longitudinal axis X having a circumference that is interrupted by two jamming tabs 45a, 45b and two locking tabs 46a, 46b.
  • the jamming tabs 45a, 45b and the locking tabs 46a, 46b, respectively, are longitudinally opposed and are projecting inwardly of the cutout 39.
  • the support panel 1 comprises jamming sections 45c, 45d defined in that upon insertion of the first connector 68 in said cutout 39 along arrow 40, the jamming items of the second type 3c, 3d protrude from the support panel 1 and the jamming slots 38 thereof open towards said corresponding jamming sections 45c, 45d. Likewise upon said insertion, the jamming items of the first type 3a, 3b protrude from the support panel 1 and the jamming slots 38 thereof open towards corresponding jamming tabs 45a, 45b.
  • the support panel 1 comprises a first locking section 47 and a second locking section 48 that communicate with the cutout 39.
  • the first locking section 47 is preferably located between the two jamming sections 45c, 45d.
  • the grommet 7 according to the first embodiment of the invention is shown in Figs. 5 to 9 .
  • the grommet 7 comprises a grommet frame 8 and a grommet sealing 9.
  • the grommet frame 8 is substantially adapted to the form of the cutout 39.
  • the grommet frame 8 thus is substantially a rectangular frame having two parallel longitudinal arms 51, 52 and two parallel transversal arms 53, 54 i.e. a first or top arm 53 and a second or bottom arm 54.
  • the grommet frame 8 has a first or front surface 55 and a second of rear surface 56.
  • the bottom arm 54 of the grommet frame 8 comprises a first locking latch 10 in form of a hook that is engageable with the support panel 1 and more particularly with the first locking section 47 of said support panel 1 that is comprised between the two jamming sections 45c, 45d collaborating with the two jamming items of the second type 3c, 3d of the first connector 68.
  • a second locking latch 18 is formed on a top section of the grommet frame 8 at the side of the top arm 53.
  • the second locking latch 18 is composed of two rear support sections 58, two intermediate support sections 17, two front support sections 15, a transversal section 60 and an elastic arm 14.
  • the two rear support sections 58 are respective protrusions of the longitudinal arms 51, 52 extending inwardly of the grommet frame 8 and in the plane of the grommet frame 8.
  • the two intermediate support sections 17 are formed on the respective two rear support sections 58 and extend from the front surface 55 of the grommet frame 8 preferably perpendicularly to said grommet frame 8.

Therefore a gap 61 exists between said first surface 59 of the second locking latch 18 and said front surface of the grommet 7 or grommet frame 8.
  • the transversal section 60 is formed between the two front support sections 15.
  • the transversal section 60 supports the elastic arm 14 that extends towards the grommet frame 8 up to an arm end 14a.

  • the bottom incline 16 is adapted to communicate with the intermediate support section 17 of the second locking latch 18.
  • the top incline 13 and lateral incline 19 do not communicate with said intermediate support section 17, but rather end on the first surface 59 of the front support section 15 and are separated from the plane of the grommet frame 8 by said gap 61.
  • the second locking latch 18 can turn around an axis defined by the rear support sections 58 or around an axis defined by the intermediate support sections 17.
  • the amplitude of this movement of the second locking latch 18 depends on the flexibility of said rear support section 58 or said intermediate support section 17.
  • the structure of the second locking latch 18 differs in that it is the top incline 13, instead of the bottom incline 16 as in the embodiment shown in Figs. 6 and 7 , that is adapted to communicate with the intermediate support section 17.
  • the second locking latch 18 is nevertheless also able to turn around an axis defined by the rear support sections 58 and/or the intermediate support sections 17.

  • the front surface 11a of the projection 11 first contacts the second locking section 48 of the support panel 1. Then, the projection 11 is pressed by the edge of the second locking section 48 and, as the grommet is turned further, the elastic arm 14 deforms resiliently and deflects towards the transversal sections 60 supporting the elastic arm 14. The projection 11 further passes the edge of the second locking section 48 when the grommet 7 is fully mounted on the support panel 1 and the elastic arm 14 return resiliently so that the rear surface of the projection 11 engages said second locking section 48.

  • the grommet frame 8' is preferably a pre-moulded plastic part that is over-moulded with the grommet sealing 9' either completely or partially, said grommet sealing 9' being preferably made of rubber.
  • Figs. 25 to 29 show the different steps of mounting the connector assembly according to the second embodiment on the support panel 1.
  • the first connector 68 is at first mounted on the cutout 39 of the support panel 1 similarly to the first embodiment, see Figs. 25 and 26 . This first step is completed as soon as the first connector 68 is fully inserted, i.e. when the jamming items 3a, 3b, 3c, 3d respectively have engaged the jamming tabs 45a, 45b and the jamming sections 45c, 45d, and when the locking latches 4a, 4b have snapped behind the locking tabs 46a, 46b.
  • Fig. 28 shows a section of the mated electrical connector 2 mounted on the support panel 1.
  • first cavities 69 of the first connector 66 communicate with second cavities 70 of the second connector 68 such that corresponding terminals (not shown) can be connected.
  • the grommet 7' is approached from the other side of the support panel 1 and the first locking latch 10 is engaged with the first locking section of the support panel 1 through the first gap 49.
  • the grommet 7' is next turned around this engagement towards the support panel 1 in order to insert the front support section 15' in the gap 50 and to let the projection 11' make a snap fit with the second locking section 48 of the support panel 1, see Figs. 26 and 27 .
  • the front incline 13' and the bottom incline 16' of said grommet 7' may slide against the support panel 1 and the top inclines 5a, 5b of the electrical connector 2. Therefore the grommet 7' can be smoothly guided through the support panel 1, see Fig. 29 .
  • Dismounting the grommet 7' from the support panel 1 and the electrical connector 2 may be achieved as for the first embodiment by first releasing the snap fit of the projection 11' of the second locking latch 18' and next unhooking the first locking latch 10.
